My colleague Harald Ueble and I are working on a repo to help especially Java developers getting started with cloud-native applications. By doing this we have learned a lot ourselves. (more…)

When running cloud-native applications in the orchestration framework Kubernetes and the service mesh Istio, microservices need to report whether they are ready and live. Kubernetes needs to know this to restart containers if necessary. Istio needs to know this information to define where to route requests to. (more…)

As defined in the Twelve-Factor-App it's important for cloud-native applications to store configuration externally, rather than in the code since this makes it possible to deploy applications to different environments. (more…)

As some of my readers will know, I'm working on a cloud-native-starter repo that demonstrates how to start building cloud-native applications with Java EE and Istio. One of the required core features for most applications is authentication and authorization. (more…)

For cloud-native applications Kubernetes and Istio deliver a lot of important functionality out of the box, for example certain metrics which are independent from the actual service implementations can be collected automatically. (more…)

Istio is an open source service mesh to connect and control microservices in cloud native applications running on Kubernetes. One of the key features is traffic management for A/B testing, canary rollouts and blue-green deployments. (more…)

Yesterday Harald Uebele, Thomas Südbröcker and I presented Blue Cloud Mirror in an IBM Developer webinar. Below are the slides and the recording. (more…)

This week I've attended JavaLand, a developer conference in Germany with 2000 attendees. It has been the fourth time I've been there and, as always, it has been a great pleasure. We had a booth where we talked with developers about what IBM offers for Java developers and how IBM contributes to the Java community, for example by supporting AdoptOpenJDK. (more…)

Last week Red Hat introduced the open source framework Quarkus which promises fast boot times and low memory usages. This makes Quarkus interesting for Java workloads running as serverless functions. (more…)
